Speaker connectors, such as banana plugs, make wire connections to speakers and amplifiers easier. In addition, these connectors create a gas-tight configuration, virtually eliminating corrosion of copper wiring due to exposure to oxygen. These connectors can be very inexpensive, and only require a crimp tool to connect. Once the connectors are applied to the wire, making or removing speaker connections becomes as simple as removing a stereo patch cable.
Strip 1/2-inch of insulation from the end of the wire. Twist the bare wires tightly in the direction of the wire's spiral.
Slide the cosmetic rubber boot over the wire and down the jacket to move it out of the way temporarily.
Slide the crimp connector over the bare wire. Position the crimp tool over the connector's collar. Squeeze firmly to secure the connector on the wire.
Slide the cosmetic boot back up the wire, and over the connector's collar. Most connectors have a notch to secure the cosmetic boot. Use that to secure the boot.
Insert the banana plug into the opening in the end of the binding posts on the amplifier and speaker.
